Tiger Woods has had two agents and three regular caddies in his 27 years on the PGA Tour. He has used four coaches and four brands of irons. The one constant always has been Nike. Woods and the swoosh were a beautiful partnership from the day he announced he was turning pro in 1996. And now that's over. Nike co-founder Phil Knight expected Woods to do for golf what Michael Jordan had done for basketball. That part was true. But Nike didn't get the bounce in business. All it got was great commercials and big moments on TV.
